From c983294872ebccd4aacf1b8dd694ac2170feadc3 Mon Sep 17 00:00:00 2001 From: "arnd@arndb.de" Date: Mon, 19 Jun 2006 20:33:34 +0200 Subject: [PATCH] [POWERPC] spufs: fail spu_create with invalid flags At this time, all flags are invalid. Since we are planning to actually add valid flags in the future, we better check if any were passed by the user.
